FS2 CONCRETE SAW — OPERATION
Saw Alignment
1.The FS2 employs a front and rear pointer (Figure 22) that has been precisely aligned with the diamond blade at the factory. Referencing the figure below, accurate tracking is accom- plished by referencing the front and rear pointer tips over the cut line. Precise saw direction is accomplished by slight operator pressure against the handle bars.

5.Set the depth and saw only as the job conditions and specifications require. Unnecessary deep sawing is wasteful to the life of your blade.
6.The preferred method of sawing is to step cut in increments of 2” (51mm).
CAUTION:
ALWAYS saw in a straight line only. Serious damage to the blade may occur if the saw is twisted or forced to cut radius shapes.
7.The rotation of the blade creates a tendency for the saw to pull in a particular direction (to the right if the blade is mounted on the right, to the left if the blade is mounted on the left).
8.To ensure a straight line of sawing, apply pressure to the
2.To reorient a pointer position, loosen the hex screw that secures the pointer bar to the shaft, adjust as necessary, and retighten the hex screw.
3.For operator comfort, an ergonomically designed handle bar adjusts by loosening two clamping knobs (page 46, item 8), and adjusts to the desired height. Tighten the knobs back down when the desired height is met.
Wet Saw Operation
WARNING
The operator must wear the appropriate protective equipment and clothing while engaged in sawing.
1.Connect hose from water source to the hose fitting connec- tion (see item 14, page 44 "Water System Assembly") on the saw. The source pressure should be approximately 40 psi.
2.Select the “flood” position on the console (Figure 6), and ensure the proper flow and rate
3.Advance engine throttle to full (FAST) position.
4.Slowly lower the blade onto your cut line by cranking the Raise/Lower handle clockwise: while observing the depth of the cut desired by referencing the depth feed gauge (Figure 6). IF the water supply to your blade is interrupted, stop sawing immediately.
appropriate handle as you slowly advance the saw forward. DO NOT force the blade to the cut any faster than its natural tendency.
WARNING
If the engine stalls for any reason during sawing, raise the blade out of the cut before restarting.
9.The operator must recognize and adhere to the optimum speed that the saw advances while sawing. DO NOT force the saw in the cut. Observe the engine tachometer from time to time to get the feel for a smooth sawing pace relative to RPM.
